Sorcière sombre steampunk préparant des potions dans une chambre lumineuse

A steampunk style fantasy art water color painting of an ultimate evil Grand Dark Witch in her incantation chambers cooking evil potions in her brass cauldron in the middle of the room. She is wearing a very shimmering black dress with leather accents with several gold amulets and has long, shiny gorgeous jet black hair. She has glowing red eyes. She is holding her magic wand. Her ancient friend, an huge dark giant rat is watch from behind her. Her room is filled with bookshelves with ancient books and skulls and thick cobwebs everywhere. The image is done in the style of the fantasy and steampunk masters in a watercolor medium. The lighting is dramatic, with a glow and eeriness in her incantation room
